Iron door bug

[Lunfeng]

I have just placed a iron door on the grass.Then it became a half door block and a grass.

This is an issue with all new doors. It is simple to fix. Just break old blocks and retry.

How many tries should it take? I've placed dozens of doors and they always come out as glitched half-doors. Should I just keep trying?

Replace the grass block under it with another grass block from inv, this fixed it for me atleast. @psifertex
